liter 4-cylinder plugin hybrid
Press Release) Audi A6 L e-tron concept
Audi is presenting its first luxury-class e-tron concept car – a
technology study known as the Audi A6 L e-tron concept at Auto China
2012 in Beijing. The plug-in hybrid has a powerful drive system that
enables a driving range of 80 km (49.71 miles) on pure electric
power, and it was specifically designed to fulfill Chinese needs.
The A6 L e-tron concept is an important step towards future electric
mobility in China for Audi. With its first e-tron technology study
in the luxury class, the company is showing what a locally produced
New Energy Vehicle from Audi might look like.
The basis for this study is the new A6 L, the most successful
premium automobile and Audi’s bestselling model in China. Audi
produces this business sedan at the Changchun plant in a joint
venture with FAW.
The A6 L e-tron concept is precisely tailored to the requirements of
Chinese customers. Plug-in hybrids that can travel long distances
electrically – thereby enabling zero emissions driving in local
areas – are ideal for use in rapidly growing megacities. Beyond its
drive system, the A6 L e-tron concept has all of the qualities that
customers value in Audi cars: prestige, comfort and sporty
Parallel hybrid system:
intelligently combined TFSI and electric motor
The technology study is
a parallel hybrid. It brings together a 2.0 TFSI that outputs 155 kW
(211 hp) and an electric motor with 70 kW (95 hp) peak power. The
liquid-cooled lithium-ion battery is located in a
collision-protected space at the rear of the vehicle. In electric
mode, the Audi A6 L e-tron concept can travel up to 80 km (49.71
miles) at a constant speed of 60 km/h (37.28 mph). At any given
moment, the hybrid control module chooses the best suited operating
mode with the focus on driving range.
This technology platform can be operated with only the internal
combustion engine, only the electric drive, or in hybrid mode. In
addition, it can recover energy during deceleration, or it can boost
output power for strong acceleration by combining the two drives.
The Audi A6 L e-tron concept delivers sporty performance.
Setting a course for the future:
Audi’s e-tron strategy
The rapid advance in
urbanization and the associated need to reduce CO2 emissions are a
key determining factor for new drive technologies. Audi views
electric mobility as a key future technology and is working on
highly efficient solutions that simultaneously offer the customer a
typical Audi driving experience.
Audi has already launched electrified drive systems in volume
production with full hybrid models that have highly advanced
lithium-ion technology. The Q5 hybrid quattro, A6 hybrid and A8
hybrid can drive up to three kilometers (1.86 miles) on electric
power. In combined mode, which uses the internal combustion engine
and electric motor, customers experience sporty driving performance
and significantly better fuel economy.
The next step is to implement drive systems in which electric
driving is the primary focus. The term Audi e-tron refers to
technologies ranging from PHEV (Plug-in Hybrid Electric Vehicle) to
range extenders and finally vehicles powered purely by electric
batteries or fuel cells.
In its first Audi e-tron concept car, Audi already showed how this
future might look. And in the case of the R8 e-tron, this vision
will be realized in a short production run later this year.
Audi is using A1 e-tron and A3 e-tron test vehicles to acquire
important customer feedback, which can be incorporated in later
production cars. The first product will be the A3 e-tron in 2014. It
will be followed by other New Energy Vehicles. In this way, e-tron
will become established as a further attractive drive technology
option alongside TDI and TFSI.
Elegant: the styling
The Audi A6 L e-tron
concept is notable for its elegant styling. The sedan, which has a
3.01 meter (9.88 feet) wheelbase, is 5.02 meters (16.47 feet) long
and 1.87 meters (6.14 feet) wide, but only 1.46 meters (4.79 feet)
tall. Its long engine hood, its low, extended roof line and the
sharp lines on its sides create an athletic overall look.
Characteristic Audi LED headlights emphasize the car’s determined
The car’s exterior styling shows its differences from the production
car. At the front, the single-frame grille with its slender
cross-bars and the nearly covered air intakes attract the eye – both
features are typical of all e-tron models. Powerful 21-inch wheels
in e-tron design and the special rear diffuser highlight the car’s
progressive character. On the body, signatures identify the
prototype’s technology, while under the engine hood a styling
capsule covers engine components. A ribbed contour at its center
symbolizes the hybrid drive.
Lightweight and strong with Audi
ultra: the body
The body of the A6 L e-tron
concept is identical to that of the Audi A6 L. It is lightweight,
rigid and safe to a maximum degree, due to application of the ultra
lightweight principle. Consisting of approximately ten percent
aluminum, it weighs about 15 percent less than a comparable
all-steel design. Aluminum components in the load-bearing structure
and exterior skin, as well as the high-tech steels used in the
occupant cell, make the body significantly lighter.
Each new future Audi model will be lighter in weight than the
previous model. This makes the brand a frontrunner in reversing the
upward weight spiral. In designing car bodies, developers will
intelligently use new combinations of materials, including carbon
fiber-reinforced polymer (CFRP). For Audi, ultra lightweight
construction does not solely focus on one material, rather it seeks
a flexible approach that utilizes a wide variety of materials – but
with one goal: to attain the best performance with the least
material usage at the best places.
Furthermore, advanced materials and construction methods achieve an
extremely low sound level in the interior of the Audi A6 L e-tron
concept. Excellent vibration comfort is attained by fine-tuning
components and by hydraulically damping axle and drive mounts.
Comfortable and sporty: the chassis
Audi’s ultra lightweight construction competence is also found in
the chassis, which combines a high level of comfort with sporty
handling. The links are made of aluminum. The power steering, like
the brake booster and the air conditioning compressor, utilizes an
At the limits of performance in driving through curves, the
electronic transverse differential lock – a function of electronic
stabilization control (ESC) – stabilizes the Audi A6 L e-tron
concept by making small interventions at the front wheel on the
outside of the curve.
Luxurious: interior and features
As in the Audi A6 L
before it, the interior of the technology platform continues the
elegant styling of its exterior design. Its defining element is an
arc under the windshield – the wrap-around – that surrounds the
driver and front passenger. The front of the instrument panel is
designed in the form of a flowing wave. All of the interior details
illustrate the aesthetic standard with which Audi builds its
vehicles. All materials have been carefully selected and
meticulously worked into the design.
The controls are intuitive. The powermeter replaces the tachometer;
its pointer indicates total drive system power on a scale of zero to
100 percent. Colored segments indicate the current operating state
of the A6 L e-tron concept; an auxiliary instrument visualizes the
charge state of the lithium-ion battery.
Meanwhile, the energy flow indicator tells the driver the current
operating mode and which hybrid drive components are currently
active. It can be called up from the driver information system or
MMI monitor. The large screen shows a bar diagram of average fuel
economy and indicates the amount of recovered energy over
The Audi A6 L e-tron concept offers a lot of space at all seating
positions. It integrates all of the model line’s luxury-class
features. The seats offer ventilation and massage functions, the
Bose surround system delivers good sound, and the deluxe automatic
air conditioning system with air ionizer ensures a pleasant climate
in the car. Ambient lighting adds subtle highlights to the interior
The driver assistance and safety systems also satisfy the highest
standards. Audi active lane assist supports the driver in
lane-keeping, while Audi side assist helps to change lanes. When it
is dark, the night vision assistant highlights detected pedestrians
even at a distance; the parking assistant helps in parking. The Audi
pre sense system can reduce the severity of accidents and their
consequences in many cases.
The car’s features also include MMI navigation plus. Many functions
of the large hard-drive navigation system can be controlled by
touchpad character input; the touch-sensitive pad, MMI touch,
recognizes 29,000 Chinese characters. A team of engineers developed
these functions at the Audi Infotainment Tech Center (ITC) in
Beijing, where infotainment components from Germany are adapted to
suit the wishes of Chinese customers.
